Figure 3 is a view of the top of my device showing a portion thereof broken away to indicate the method of mounting and driving various parts.

Figure 4; is a transverse section through the dispersing tank 13, and showing a portion of the bottom of the tank 13 broken away to exhibit the oppositely rotatable fans.

Like parts are identified by the same reference characters throughout the several views.

I am aware that means for renewing the air in submarines have heretofore been provided, however, I have found that a device constructed according to the disclosure hereinafter set forth is much more efficient of operation and actually supplies more available oxygen to a compartment containing vitiated atmosphere than has heretofore been possible with any other device. In the de- 1. vices heretofore provided water was admitted in the form of spray into a compartment in which a partial vacuum was maintained, and the oxygen secured from the water has been conveyed to other parts of the submarine or other vessel through the mechanism for maintaining the partial vacuum. My device is much more eflicient than such devices.

Various working parts of my improved air if) renewing structure are contained and operated in an enclosure into which water is introduced through a pipe 11 and from which water is released or pumped through a pipe 12. Within the closure 10 are provided three on principal units each performing a definite 1928. Serial No. 290,317.

function in connection with my device, in the order in which the. various parts function upon water introduced through the pipe 11, these three units are as follows:

First, a container 13 comprising side walls in any desired shape and a perforated bottom 14. In the specific structure shown in Figure 1 I have shown a tubular insert 15 throu h which a power shaft 16inay pass for tie transmission of power from above the container13 to a point below thecontainer where a second unit of my device is installed.

Below the perforated bottom 14 of the container 13 the second unit of my structure is constructed. This unit comprises a set of oppositely rotatable propellers or fans 17 and 18, one of these fans 17, being mounted for rotation directly upon the shaft 16 and the other 18, being mounted for opposite rotation upon a hub or sleeve 19, power being transmitted to said sleeve 19 through gears 20, 21 and 22, gear 22 in turn being mounted upon a power shaft 23 driven through bevel gears or otherwise from a motor 24 as shown at 25. Surrounding the propellersor fans 17 and 18, I provide a perforated shield 26 which has no bottom and which is, therefore, formed in the shape of a perforated cylinder mounted upon a bracket 27 secured to the side wall 13 of the first receiving unit described above.

The third and last unitof my device a fan 28 mounted in an aperturein the wall of the compartment 10, saidfanbeing mounted for rotation upon a shaft 29 supported by bracket 30 so as to receive power through bevelpinions 31 and 32. I

g This fanr28 is an evacuating fan acting upon air within the compartment 10. I

A As stated above my device is adapted f0 use in submarines and I have, therefore, shown my device mounted withinthe wall 35 of a submarine andI have shown that pipe 11 is so constructed as to carry water from without the submarine through a globe valve 36 into the first unit of my} device within the compartment 10.

In operation my device functions as follows: Water admitted through the pipe 11 into the container 13 passes in the form of small drops downwardly through the perforated bottom of said container Where the fans 17 and 18 revolving oppositely under the power transmitted from the motor 24 through gears 37 and 38 at the top of my device and through gears 20, 21, and 22 through shaft 16 and sleeve 19, respectively, disperse the drops of Water in-the form of mist. These fans swirl the drops of waterhoutwardly ultimately against the perforated cylinder 26 through which a constant spray is induced and from which finely divided particlesof Water pass into the atmosphere into .themain tompartment 10.

The atmosphere of theinain compartment 10 is maintained at a slightly reduced pressure'xby reason ofthe operation of theevacua'tingLfan 28 with a resultthat' all oxygen extracted or impacted fronitlre Waterby the revolving parts of my device is'passed into the main body "ofthe submarine or other vessel tobe made 'avail'able' for any purpose desired.

I have found that each of the several units of these described is invaluable for the purpose for I have found that if any of the fans or-=propellers =17, 1801 28 are stopped the proper functioningof my device is seriously impaired and that whereas-my entire device w'illreplenish atmosphere in an air tight vessel to maintain life or to maintain combustion, the-device Willneither maintain life or combustion if any one of said units is dispensed With ordiseonnected from normal operation as described.

' I claim:

1-. In the device'of the character described anapertured'compartment, a fanin the aperture of said "compartment for maintaining a reduced atmospheric pressure, a' container within the compartment provided With an apertured wall section, oppositely rotatable fans adjacent-said wall section, a shaft through the container and secured to one of said fans to provide-an axis of rotation for said fan; asleeve secured tothe other said fan and rotatable-about said shaft, a power shaft provided with spaced gears, and gears upon'said sleeve and shaft to interact upon saidpower shaft,- Whereby to operate said 'l'ansoppositely.

2. In a device of the character described, an apertnred compartment provided With a water inlet, afan inthe aperture of'said compertinent forunaintaining a reduced atmospheric pressure-therein, a container Within the conn artment supplied with Water from the inlet andprovided With an apertur'ed Wall section, oppositely rotatable fans adjacent saidgwall section, and a foraminous shield partially snr-ro unding said fans.
